What are the typical elements of a process image?

User data: Modifiable part of user space. May include program data, user stack area, and programs that may be modified.

User program: The instructions to be executed.

System Stack: Each process has one or more LIFO stacks associated with it. Used to store parameters and calling addresses for procedure and system calls.

Process control Block (PCB): Info needed by the OS to control processes.

What is the most recent Windows Operating System software available?

Windows 8 for home, business and portable is the most recent Windows Operating System software. It was released in 2012 and features a new touch interface and is designed to be more compatible with mobile devices such as tablet and notebook computers.

Which is more important application or operating software?

Operating system is more important than the application software, in the sense that the operating system is the mother of all software that are to run on the computer. without the operating system, it is impossible for the computer to run. operating system provides a platform for all other software to be installed on. it is actually the main software that supports all other software.

What is the main character of the Linux Operating system?

Linux is, as you noted, an operating system. It is not a game so it does not have a main character. However, different distributions have different mascots. For example, the mascot for SUSE Linux is a lizard of some sort. The mascot for Linux in general is usually stated to be a penguin named Tux

What are the main purposes of of an operating systems?

It is used to operate the computer well besides we need a software to run in our system . run software and games we need the help of the o/s ( win xp,win7, win vista etc)

Why did Apple choose to name their computer Macintosh (Mac)?

Apple employee Jef Raskin is responsible for coining the machine after his favorite variety of apple, smartly tying the whole fruit theme together.

What is the difference between operating system software utility software and application software?

  • An operating system is the software that bridges the gap between the system and the user.
  • Utility software performs actions essential for protecting, guiding, securing, and storing information or data appropriately in the system.
  • Application software manages specific actions, for example, browsers, word processors, etc.

Would you set up a GUI on a server system?

Not sure what this means. But SSR is a relatively new but extremely important feature of modern web apps.

Advantages layered architecture operating system?

The O.S has been divided into different layers and each layer has mentained some hierarchy.

What was the first operating system?

The earliest computers did not use operating systems; a simple loading program was loaded into the computer - via front panel switches or punched tape, the loading program would load the actual program to run. The program would take over the entire machine until it halted or was interrupted by the operator.

This process of loading programs from storage was automated, to some extent, in the 1950s and MIT may be able to claim the earliest such system in 1954 (see attached link).

This is one of the things no one will ever know for sure. When I developed software for the IBM 704 in conjunction with a missile guidance project in 1957, I had never heard of an operating system but I eventually realized that that's what I had created. It's written up in the Annals of the History of Computing, Volume 11 (1989). I can't say that it was first, but it was early, and I don't know any older ones.

In 1961, Burroughs introduced the MCP (Master Control Program) for its B5000 mainframe computer. These early operating systems were little more than loaders. With the advent of high speed disk drives, virtual memory systems and disk control systems became more widely used.

In 1969, Unix was being developed. Unusually for the time, Unix was designed to run on different machines, small device drivers were written for specific hardware, but the bulk of the code was unchanged.

The first microprocessor operating system was CP/M; as with Unix by separating the hardware dependent parts of CP/M from the majority of the code, it made it easy to port CP/M to different hardware platforms (although it was written for the 8080 family of microprocessors).

What is the importance of operating system?

An operating system provides an interface between the hardware and the user. It allows us to use computers without having to know how to program them.

Can you open a website in dos operating system?

MS-DOS and most clones do not include a web browser in their core utilities. There are a few web browsers available for MS-DOS, but setting up and installing a packet driver for a network card in DOS is only slightly less difficult than cutting off your arm with a toothpick. The web browsers available also don't render most modern web pages correctly, and the performance is abysmal.

What operating system does IBM use?

IBM System z servers are supported by a multitude of operating systems, such as z/OS, z/VSE, z/TPF, Linux on System z and the z/VM hypervisor.

Define deadlock in operating system?

In order for deadlock to occur, four conditions must be true.

  • Mutual exclusion - Each resource is either currently allocated to exactly one process or it is available. (Two processes cannot simultaneously control the same resource or be in their critical section).
  • Hold and Wait - processes currently holding resources can request new resources
  • No preemption - Once a process holds a resource, it cannot be taken away by another process or the kernel.
  • Circular wait - Each process is waiting to obtain a resource which is held by another process.

What are the differences between deadlock avoidance and deadlock prevention in operating systems?

Deadlock Prevention:

o Preventing deadlocks by constraining how

requests for resources can be made in the system and how

they are handled (system design).

o The goal is to ensure that at least one of the

necessary conditions for deadlock can never hold.

*

Deadlock Avoidance:

o The system dynamically considers every request

and decides whether it is safe to grant it at this point,

o The system requires additional apriori

information regarding the overall potential use of each

resource for each process.

o Allows more concurrency.

Similar to the difference between a traffic light

and a police officer directing traffic.

* Deadlock deduction:-

Often, neither avoidance nor deadlock

prevention may be used. Instead deadlock detection and

process restart are used by employing an algorithm that

tracks resource allocation and process states, and rolls

back and restarts one or more of the processes in order to

remove the deadlock. Detecting a deadlock that has already

occurred is easily possible since the resources that each

process has locked and/or currently requested are known to

the resource scheduler or OS.

Detecting the possibility of a deadlock before it occurs is

much more difficult and is, in fact, generally undecidable,

because the halting problem can be rephrased as a deadlock

scenario. However, in specific environments, using specific

means of locking resources, deadlock detection may be

decidable. In the general case, it is not possible to

distinguish between algorithms that are merely waiting for a

very unlikely set of circumstances to occur and algorithms

that will never finish because of deadlock.

Deadlock detection techniques include, but is not limited

to, Model checking. This approach constructs a Finite

State-model on which it performs a progress analysis and

finds all possible terminal sets in the model. These then

each represent a deadlock.

Why is the book operating system concepts the dinosaur book by silberschatz galvin gagne called a dinosaur book?

Because there is a picture of a dinosaur on every version of the text, from the very first edition. It is now on its seventh or eight printing, and has always had some variation of dinosaurs on the cover.

What is the best Linux desktop based operating system to install on Fujitsu Siemens Amilo Pi1505 laptop?

Different people have different opinions on what distro is best. That's why there are so many. Ubuntu is the most popular distro, due mainly to it's shipping of free CDs, but it is not the only one. Kubuntu, Xubuntu, PCLinuxOS, Mandriva, Freespire, and OpenSUSE are all widely regarded as easy to use / learn. I suggest trying as many distros as you can, to get a feel for the wide variety, and see what you like or don't like in each of them.

As far as hardware support goes, it's pretty much universal across all major distributions. So none is better or worse suited for your hardware. Due to your processor, you will not be able to use any 64-bit distros.
